SEINE NEEDLE I Filed March 8, 1958 Patented Jan. 17, 1939 UNITED STATES PATENT OFFICE SEINE NEEDLE Walter Ostcrback, Sand Point, Alaska Application March 8, 1938, Serial No. 194,689

2 Claims.

This invention relates to seine needles or needles or shuttles used in making nets, and the general object is to provide a seine needle with a knife which forms part of the needle and which 5 is normally in a retracted. position within the boundries of the needle but which may be projected into active position.

My invention is illustrated in the accompanying drawing wherein:-

10 Figure 1 is a side elevation of a seine needle constructed in accordance with my invention.

Figure 2 is a top plan view thereof. Figure 3 is an enlarged fragmentary elevation showing the knife in its projected position.

Referring to the drawing, l designates the seine needle itself having the usual form, that is, pointed at one end, as at 'l I, and recessed at its butt end, as at I2. One side face of the needle I0 is formed with a recess 13 and disposed within 20 this recess is the knife blade M which is pivoted to the body of the needle at [5. This knife blade has its back contour such that it extends toward one edge of the needle I0 and this edge of the knife blade is provided with the laterally project- 25 ing stop l6. When the knife blade is retracted and entirely within the recess I3, the stop l6 fits within a notch I'l formed in the edge of the needle. When the knife blade is projected into the position shown in Fig. 3, the stop l6 rests against 30 the edge of the needle.

In the ordinary use of the needle, of course, the knife blade is retracted into the recess I3 and has no projecting portion which would be likely to catch on the cord being netted, but when it is desired to use the blade, it is turned outward to the position shown inFig. 3, with the stop It resting against the edge face of the blade. Where a seine is being netted, a knife is always in constant use and for the purpose of cutting the cords at the knots or in the course of manufacturing the same. By the provision of this blade, it is possible for the needle to be drawn rearward to cut a cord without thenecessity of using an 10 extra knife.

What is claimed is:

1. A seine needle of the character described, having a knife blade pivoted to the body of the needle, the knife blade when depressed being disposed below the surface of the needle, the blade having a stop adapted to engage the edge of the needle and maintaining the blade when moved in one direction to approximately a right angular relation to the edge of the needle.

2. A seine needle of the character described,

. having a recess in one face and opening through an edge thereof, a knife blade pivoted in said recess to swing therefrom to a right angular relation with said edge, the back of the blade having a transversely extending tongue forming a stop, the edge of the needle having a recess: to receive the stop, said stop bearing against the edge face of the needle when the blade is turned out into a position approximately at right angles to the needle.
